NOTE:The fuel injector locking sleeves must be fully loosened in order to remove the fuel injectors. Loosen the fuel injector locking sleeves and remove the fuel injectors by gently working them loose. | | -
CAUTION:Remove the cylinder head bolts in the sequence shown. Remove the cylinder head. - Discard the gasket and the bolts.
| Installation | -
Clean the mating faces of the cylinder head and cylinder block with Loctite 7070. | | -
NOTE:Measure the piston protrusion of each cylinder at top dead center (TDC). Measure the distance between the piston crown and the cylinder block at the points indicated. | | -
NOTE:The largest measurement determines the choice of the cylinder head gasket. Using the special tools, measure the piston protrusion. | | -
Determine the cylinder head gasket. For additional information, refer to Specification - in this section. | | -
CAUTION:Install new cylinder head bolts. Install the cylinder head. - Tighten the bolts in the sequence shown in eight stages.
- Stage 1: Tighten bolts 1 through 10 to 10 Nm.
- Stage 2: Tighten bolts 11 through 18 to 5 Nm.
- Stage 3: Tighten bolts 1 through 10 to 20 Nm
- Stage 4: Tighten bolts 11 through 18 to 10 Nm.
- Stage 5: Tighten bolts 1 through 10 to 40 Nm.
- Stage 6: Tighten bolts 11 through 18 to 20 Nm.
- Stage 7: Tighten bolts 1 through 10 to 180 degrees.
- Stage 8: Tighten bolts 11 through 18 to 180 degrees.
